Description
Technical Field
The utility model belongs to the technical field of liquid crystal display equipment backlight system membrane structure, concretely relates to reflection film structure of area heating function in backlight system.
Background
The liquid crystal display device is an important device of information equipment and is one of the main ways for finally acquiring information in the process of man-machine interaction, but the adaptability of the liquid crystal display under a complex environment is always an important factor for limiting the development of the liquid crystal display.
The traditional scheme for solving the problem of low-temperature display abnormity of the liquid crystal display is mainly to directly heat the liquid crystal panel through ITO glass. The ITO glass has too high temperature rise rate and too high temperature, and has great influence on the reliability and the service life of the panel polaroid.
Therefore, it is necessary to provide a reflective film structure with a heating function in a backlight system, so as to effectively solve the above problems.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned problem that exists among the prior art, the utility model provides a reflective membrane structure of area heating function in backlight system has liquid crystal display equipment can be safe the characteristics of being used for a long time.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a take reflective film structure of heating function in backlight system, frame main part before the LCD screen, be equipped with the backlight cavity in the frame main part before the LCD screen, be provided with liquid crystal display panel body, optics membrane material, light guide plate main part, reflective film and conductive film in the backlight cavity.
As the utility model discloses a take preferred technical scheme of reflective membrane structure of heating function in backlight system, the liquid crystal display panel body the optical film material the light guide plate main part the reflective membrane with the conductive film is arranged from top to bottom in proper order.
As the utility model discloses a take preferred technical scheme of reflective film structure of heating function in backlight system, the backlight cavity with position department between the light guide plate main part has installed the LED light source.
As a preferred technical scheme of area heating function's reflectance coating structure in backlight system, the both sides face of reflectance coating respectively with the light guide plate main part with the surface of conductive film contacts, the both sides face of optics membrane material respectively with the liquid crystal display panel body with the surface of light guide plate main part contacts.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses when using, the reflective film is in the system of being shaded at the lower floor, through being close to the attached conductive film of structure side at the reflective film, draws forth the electrode, and when the display was during operation under low temperature environment, the work production heat was opened to the conductive film, and on the heat progressively transmitted the panel, traditional scheme panel instantaneous heating was too big can be solved to this scheme, rate of rise too fast problem to solve traditional scheme panel reliability and problem that the life-span is low.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the principles of the invention. In the drawings:
fig. 1 is a schematic cross-sectional structure diagram of the present invention.
In the figure: 1. a liquid crystal screen front frame main body; 2. a backlight cavity; 3. an LED light source; 4. a liquid crystal panel body; 5. an optical film material; 6. a light guide plate main body; 7. a reflective film; 8. a conductive film is provided.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Examples
Referring to fig. 1, the present invention provides the following technical solutions: the utility model provides a reflective membrane structure of area heating function in backlight system, frame main part 1 before the LCD screen, be equipped with back light chamber 2 in the frame main part 1 before the LCD screen, be provided with liquid crystal display panel body 4 in the chamber 2 in a poor light, optical film material 5, light guide plate main part 6, reflective film 7 and conducting film 8, in this embodiment, liquid crystal display panel body 4, optical film material 5, light guide plate main part 6, reflective film 7 and conducting film 8 arrange from top to bottom in proper order, LED light source 3 has been installed to the position department between chamber 2 in a poor light and light guide plate main part 6, the both sides face of reflective film 7 contacts with the surface of light guide plate main part 6 and conducting film 8 respectively, the both sides face of optical film material 5 contacts with the surface of liquid crystal display panel body 4 and light guide plate main part 6 respectively.
The reflective film 7 in the backlight system is at the lowermost layer of system, and at reflective film 7 near structural part side attached has conductive film 8, draws forth the electrode, and when the display worked under low temperature environment, conductive film 8 was worked and is produced the heat, and the heat progressively transmits to the panel on, and this scheme can solve traditional scheme panel instantaneous heating too big, and rate of rise is too fast problem, and the practicality is strong.
The utility model discloses a theory of operation and use flow: the utility model discloses in the in-process of using, the part of conducting film 8 is attached on reflectance coating 7, and when circular telegram during operation, the heat transmits optical film material 5 through light guide plate main part 6 of one side, transmits on liquid crystal display panel body 4 of a side of liquid crystal display front bezel main part 1 through optical film material 5 at last, and then has avoided the problem that the part of liquid crystal display panel body 4 directly contacts with the heat source and heat rate is very fast to reach the risk that the heating glass temperature is higher than liquid crystal display panel polaroid operating temperature scope under the condition of traditional scheme heating;
the method is also used for solving the problems of abnormal display of the liquid crystal display, such as tailing and afterimage, in a low-temperature environment.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
